JY series Digital pressure gauge piston dead weight tester
calibration for oil industry with 100Mpa high pressure
Description of JY series dead weight tester
JY Series Digital Pressure Gauge Calibration with 100MPa Piston
Deadweight Tester for Oil Industry** Developed per JJG59-2007
standards, the JY Series piston pressure tester features tungsten
carbide piston components—high-hardness, low-thermal-expansion—to
ensure minimal deformation under pressure and stable performance.
Using low-viscosity isooctyl sebacate as the medium, it achieves
high sensitivity even at 100MPa. This new-design tester enhances
technical metrics via advanced materials and technology, ideal for
calibrating digital pressure gauges, transmitters, sensors, and
precision instruments in high-pressure oil industry applications.

Features & Application
1. Precision Components:
The piston-cylinder assembly, crafted from high-strength carbide
tungsten carbide with low thermal expansion, ensures stable
operation across a wide temperature range (optimal at 20 ± 5 ℃).
2. Enhanced Accuracy:
With a low center of gravity, weights act directly on the piston,
minimizing pressure fluctuations and enabling precise readings.
3. High-Pressure Performance:
For pressures exceeding 25MPa, low-viscosity isooctyl sebacate as
the medium boosts sensitivity, ensuring reliable measurements.
4. Quality Materials:
Weights made from non-magnetic stainless steel prevent
interference, while a piston displacement sensor maintains accurate
positioning within ± 1.5mm.
5. Versatile Range & Adjustability:
Covering 1MPa to a domestic-leading 100MPa with ± 0.02%–0.05%
accuracy, it allows effortless pressure adjustment even at 500MPa.
